Underpinning is the process through which faulty or improperly developed foundations can be repaired. Underpinning can also be used to increase the foundation depth for an object. One of the tell tale signs that an object or building may need underpinning services is when crack become visible within the object. When foundation cracks are greater than a certain specification, this may indicate signs of an improper or faulty foundations in which case underpinning services may be required.
Residential or commercial objects may also consider underpinning if they plan on expanding their current object by adding additional stories. Additional stories would require additional support to maintain the structure and to prevent future damage i.e. cracks.
There are a number of other similar services such as foundation repair and slab jacking that can be provided. It is important to note that services like these need to be adequately assessed, appraised and analysed before a quote can be provided. Similarly, materials may need to be gathered before a job can be started (see below for variable and fixed costs).
Here’s an excerpt from an online enquirer:
‘An underpinner who has been doing this for a long time came and inspected my double storey home. After drawing up a plan and recommending five concrete pours underneath the extension, he quoted $13,500 -$15,000. Since he has a structural engineer on board and other workers, the quote won’t require me to find additional workers. While it does seem an expensive project, the only alternative is to let the cracks get wider which isn’t ideal.’
Slabjacking is a custom and special concrete repair technology. The process involves lifting a sunken concrete slab by pumping a grout through the concrete. This effectively pushes up the slab from below.
Slabjacking is a complicated process and there are usually high costs associated with it. Fixed costs for providers include slabjacking production trucks which can cost in excess of six figures. Then there are also labour, insurance as well as other overheads. The amount of gout material used for the job will form part of variable costs. Projects with large voids (which take more material to lift) will present additional cost to the provider, which will be on-charged to the client.
Other variables such as hole patching may also affect the overall cost of a job. With so many variables, it is important the service provider has a proven track record and sound experience with slab jacking. Otherwise, the service may be less than satisfactory.
